I got some good news.
A new growing friend called me to see if I could get rid of aphids.
I went to his grow and found he had branches too close to the grow medium and found the aphids nesting there and in the grow medium under this branch. I trimmmed the lower branches and sprayed and he is now after three days spraying aphid free. He will keep spraying untl all eggs hatch.
I have never seen leaf aphids living and breeding in the top of the grow medium like this. I am a noob so it is probably just new to me.
He is a dwc with a small pots with pearlite and clay balls as a grow medium and the bugs were in the clay balls.
Has anyone had the problem befor????
Very cool that it worked with all organic spray.
